SKEIN-DYEING MACHINE.

Specification of Letters Patent.

Application filed November 11, 1908.

Patented Nov. '7, 1911. Serial No. 462,120.

To all whom it may concern.

Be it known that I, WILLIAM H. FLETCHER, a citizen of the United States, and resident of Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Skein- Dyeing Machines, of which the following is a specification.

My invention relates to improvements in the manner of dyeing skeins ofsilk, cotton or other similar fabric.

The objects of my invention, are first, to-

economize on the cost of handling, and the amount of liquid used in dyeing; second to dye evenly and without tangles in the thread; third to facilitate too rapid loading and unloading of the machine. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is a dye tub with my invention attached and forming apart thereof. Fig. 2 is an end view of Fig. 1. Fig. 3 is a view of the frame on which the skeins are placed. Fig. 4 is an end view of Fig. 3. Fig. 5 is an end view of the frame on which the skeins are placed, without the frame support. Fig. 6 is a side view of a part of Fig. 5. Fig. 7 shows a side view of the frame support. Fig. 8 is an end view of Fig. 7. Fig. 9 is a section on an enlarged scale, of a part of the frame through one of the rods which hold the skein. Fig. 10 is a view of a bracket for holding the bar which retains the skein rods or sticks in the frame. Fig. 11 is a View of the above mentioned bar. Fig. 12 represents two views of a catch which prevents the frame from revolving in its supports. Fig. 13 is a spring catch which holds the bar. in the bracket shown in Fig. 10. Fig. 14 represents two views of a cam which operates the frame in the dye box.

Similar numerals of reference indicate corresponding parts throughout the several views.

In the drawings, 1 represents the frame which supports the raising, lowering and vibrating devices. The means for raising and lowering the skein holding frame, consists .of chains 18, upper ends of which are secured to the frame supports, arms 25, the other ends of the chains are secured and wound around the drums 8 on the shafts 19. The shafts 19 are secured to the upper part of the frame 1. On the one end of the two shafts 19 a worm gear 10 issecured and is operated by a worm 11 on the shaft 12. The shaft 12 can be operated by power by means of the tight and loose pulleys 13 or by means of the handle 17, the sprocket wheel 16,the chain 15, and the sprocket gear 14 on the said shaft 12, so that the said lifting can be operated either by power or by hand.

The frame with the skeins is oscillated in the dye liquid by means ofacam 20 in which there is a groove 21 in which a stud or roller acts, this stud or roller being secured to a lever 22 at a point 23. The cam is revolved by means of the pulley 6 and the gear 4 on the same shaft acting in the gear 3 on the cam shaft 7. The action of the cam communicated to the lever 22 and then to the frame by means of the bar 9 is such that the frame holding the skeins will remain in one position in one end of the box 2, and then make a rapid move to the other end and then back so as to agitate the liquid with as little disturbance to the threads of the skein as possible.

The frame supports consist of two bars 26 secured at a distance apart by rods 27 and 36 and on each of the ends of the bars 26, arms 25 are extended upward, and the chains 18 are secured to them. The frame swings on the said chains. On each arm there is an L-shaped catch 29, with the bottom portion 30 coming in contact with the frame for holding the skeins to prevent the said frame from turning when unloading, or when not desired. The roller 24 on the rod 36 receives the lever 9 when it is desired that the frame should oscillate. The hangers on each side indicated by 28 are secured to the bars 26 and the frame for holding the skeins revolves in the frame holder by the studs 34 turning in the hanger 28 at the bearing 59.

The frame for holding the skeins consists of four long pieces 37, two on each side, the two on one side are held in position by upright pieces 48, one on each end, and the upright piece 49 in the center, and the sides are held by the cross pieces 46. The pieces 37 one on the top and the other on the bottom have slotted openings part the way through, indicated by 45, in which are supported the sticks 46 on which the skeins 35 hang, two sticks to each group of skeins, one upper and the other at the bottom. The sticks with the skeins are retained loosely in the openings -15, by the bars 38 which slide in position on top of each long piece 37 and under the portion 40 of the bracket 41. The port-ions 40 are screwed to the inside of the piece 37 the notches 39 fitting around the said bracket 4-1, and are held there by the spring 42 which is pivoted, or swings on a bolt through the hole at on the piece 37, and has a small button 43 which keeps the spring in place. In the center of the upright piece 49 there is a pin or stud as on each side of the frame which rest in the hangers 28 and on these the frame can revolve in the dye tub freely. lVhen the inner frame is loaded with goods it is desirable to have it revolve as much in the liquid as possible and it may also revolve when elevated.

To load the machine the skeins are hung on sticks preferably wood, the same as usually used in dyeing by hand; two sticks are used for each group of skeins, the one in the upper pieces 87, and the other in the corresponding lower pieces 37. The skeins hang loosely on these sticks 46 and when the frame is revolved as indicated by the line 31, or the reverse way the skeins change their position or point of cont-act with the sticks, this they do natural and thus avoid marking from the wood and insure an even dye. To prevent the skeins from coming in contact with any of the frame or any metal,

guide rods are secured lengthwise in the frame, these are of glass or some substance which will not hold color. tunning crosswise in the frame and also secured to the frame are guide rods 51, similar to the rods 50, which serve the same purpose in the ends of the frame.

To unload the machine, the spring pieces as are turned down out of the way, and the bar 38 withdrawn, the sticks 46 with the skeins can then be lifted out.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a skein dyeing machine an inner frame consisting of top and bottom skein stick holders connected rigidly by means of cross bars 47 and upright pieces 48 and a center piece 49 on which the axis is situated centrally in connection with an outer frame support, which consists of longitudinal bars 26 secured together by cross rods 27 on up right arms 25, and hangers 28 which provide bearings for studs 34 as set forth and described.

2. In a dyeing machine, holders with slotted openings, skein sticks in said top and bottom openings, brackets 41 in connection with stick holders and bars 38 with notches 39 and spring catches l2 securing said bars, in connection with an outer frame support, with chain connecting arms and a hanger 28 which supports the studs 34-, and a horizontal holding catch 29 as set forth and described.

3. In a dyeing machine, a revolving frame for holding the goods, comprising slotted bars for supporting skein holders with means for securing and means for removing said bars with the skeins from the frame in which the skein holding frame revolves, oscillating means comprising cams, gears and pulleys, in combination with an open dye vat to which none of the mechanism is secured, and means for removing the skein holder with the skeins vertically from the liquid, consisting of pulleys, gears, worms, shafting and drum secured to an overhead frame work as set forth and described.

Signed at Paterson in the county of Pas saic and State of New Jersey this 10th day of Nov. A. D. 1908.
